Beaina Wearable Pump Parts for MomMed S21/S18 – Duckbill Valves, Silicone Diaphragm, 24mm Flange, Milk Collector (2 Sets)

Overview

Beaina Wearable Pump Parts are crafted to work with MomMed S21 and S18 wearable pumps, delivering a cohesive, simple-to-use setup. The package includes two complete sets: duckbill valves, a silicone diaphragm, a 24mm flange, and a milk collector cup. All parts are made from BPA-free, food-grade silicone, giving you a safe, flexible option for daily use.

How it works

The design emphasizes controlled milk flow and reliable seal. The duckbill valves create a one-way path that helps prevent backflow, while the silicone diaphragm and soft shield contribute to an airtight seal during pumping. Together, these elements support consistent suction without leaks.

• Leakproof performance: one-way flow limits spills and helps maintain suction.
• Comfort and safety: food-grade silicone and BPA-free materials touch your skin only with a soft, flexible surface.
• Minimal parts, easy cleaning: an all-in-one design reduces setup steps and accelerates post-pump care.
• Capacity and sizing: the milk cup holds up to 150ml / 5oz, and the 24mm flange is included for a common fit.

What’s included and fit guidance

Each kit includes two complete sets, so you can swap parts between sessions or rotate clean parts for quick reuse. Choosing the right flange size matters for comfort and efficiency—match the flange to your anatomy to help form a reliable seal during pumping.

• Two full sets of parts: duckbill valves, silicone diaphragm, 24mm flange, milk collector cup.
• Two 24mm flanges included for immediate fit testing and replacement.
• Capacity up to 150ml (5oz) per cup for longer pumping bursts without frequent stops.

Care, safety, and care tips

Care is straightforward thanks to the reduced number of parts. Rinse with warm water, use mild soap, and air-dry completely before reassembling. Store in a clean, dry place to preserve silicone elasticity between uses. The BPA-free material is designed to be gentle on skin and safe for regular handling.

Real-world use cases

Ideal for busy parents who pump during commutes, office breaks, or late-night sessions. The two-set design allows you to keep a clean pair ready while you wash the other, reducing downtime between uses. The soft silicone surface helps reduce pressure points during extended pumping sessions.
